Alexander the Great was one of the first world emperors of ancient era. He dreamt his future and decided to build his own empire. He started his military campaign from Small Asia (today’s Çanakkale) and conquered almost whole Asia and North Africa.
If we could travel in time and wanted to go that period, probably you would face a developed Greek civilization and powerful army of Alexander. He came to Gordion (today’s Central Anatolia). There was a knot that couldn’t be untied for a long time. According to the myth, the person-who would achieve this goal- would be the conquerer of the world. He did it by his sword. Then he established his world empire. Oracle became true. That could be interesting to witness that scene.
I recommend you to imagine it.
